Consider the father pushing a playground merry-go-round. He exerts a force of 250 Nat the edge of the 50.0-kg merry-go-round, which has a 1.50-m radius. Calculate theangular acceleration produced (a) when no one is on the merry-go-round and (b)when an 18.0-kg child sits 1.25 m away from the center. Consider the merry-go-round itself to be a uniform disk with negligible friction.
